Strip comments from UMD_PROD and NODE_PROD builds, not FB_PROD (#9776)

This regressed with the recent addition of RN_* bundles. I was accidentally stripping comments from FB_PROD when I meant to do the opposite. This corrects that mistake.

No significant bundle size change occurs when re-running this build against the version prior to the RN_* bundles.
